This patch fixes a few minor things:
- Previously ip[46]_input was rejecting packets with an input TTL (hop
limit) of one; this was not correct behavior. Packets that are bound
for this device can validly have a TTL of one.
- ip[46]_forward was not generating an ICMP TTL expired message if the
act of decrementing the TTL caused it to become zero. This was not
previously an issue because ip[46]_input was filtering packets where
this could happen.
- udp_local was not generating ICMP Port Unreachable messages if
UDP packets arrived for a port that is not listened to. This is
typically the signal that "traceroute" uses to terminate its
search.
Together these fixes mean that traceroute probes transiting a VPP
node, or are targetted toward a VPP node, now work as expected.

This change-set enables plugins to add themselves to the ip4/ip6
feature subgraphs without having to modify core vpp engine code
at all. Add VNET_IP4/IP6_UNICAST/MULTICAST_FEATURE_INIT macros
which express the required ordering constraints, and off you go.
Along the way, added an implementation of Warshall's algorithm to
vppinfra; to compute the positive transitive closure of a relation. In
this case, the relation is "feature A runs before feature B."
With that in hand, ip_feature_init_cast(...) computes a partial order
across the set of configured feature subgraph nodes.
In unit-testing, we discovered VPP-145 - ip4/6 inacl wiped out
vnet_buffer(b)->ip>current_config_index, which exists in main. So, we
fixed that by moving b->trace_index, adding b->current_config_index,
and removing the ip opaque union current_config_index.

* compiler -march= parameter is changed from native to corei7
so code is always genereted with instructions which are available
on the Nehalem microarchitecture (up to SSE4.2)
* compiler -mtune= parameter is added so code is optimized for
corei7-avx which equals to Sandy Bridge microarchitecture
* set of macros is added which allows run-time detection of available
cpu instructions (e.g. clib_cpu_supports_avx())
* set of macros is added which allows us to clone graph node funcitons
where cloned function is optmized for different microarchitecture
Those macros are using following attributes:
__attribute__((flatten))
__attribute__((target("arch=core-avx2)))
I.e. If applied to foo_node_fn() macro will generate cloned
functions foo_node_fn_avx2() and foo_node_fn_avx512() (future)
It will also generate function void * foo_node_fn_multiarch_select()
which detects available instruction set and returns pointer to the
best matching function clone.
